Josephson Effect and Charge Distribution in Thin BiTe Topological Insulators
Martin P. Stehno, Prosper Ngabonziza, Hiroaki Myoren +1
Thin layers of topological insulator materials are quasi-two-dimensional systems featuring a complex interplay between quantum confinement and topological band structure. To unders…
Magnetoresistance from time-reversal symmetry breaking in topological materials
J. C. de Boer, D. P. Leusink, A. Brinkman
Magnetotransport measurements are a popular way of characterizing the electronic structure of topological materials and often the resulting datasets cannot be described by the well…
Origin of the butterfly magnetoresistance in ZrSiS
J. A. Voerman, L. Mulder, J. C. de Boer +4
ZrSiS has been identified as a topological material made from non-toxic and earth-abundant elements. Together with its extremely large and uniquely angle-dependent magnetoresistanc…
Multiple Andreev reflections and Shapiro steps in a Ge-Si nanowire Josephson junction
Joost Ridderbos, Matthias Brauns, Ang Li +4
We present a Josephson junction based on a Ge-Si core-shell nanowire with transparent superconducting Al contacts, a building block which could be of considerable interest for inve…
Hard superconducting gap and diffusion-induced superconductors in Ge-Si nanowires
Joost Ridderbos, Matthias Brauns, Jie Shen +8
We show a hard induced superconducting gap in a Ge-Si nanowire Josephson transistor up to in-plane magnetic fields of mT, an important step towards creating and detecting Maj…
Stabilization of the perovskite phase in the Y-Bi-O system by using a BaBiO buffer layer
Rosa Luca Bouwmeester, Kit de Hond, Nicolas Gauquelin +3
A topological insulating phase has theoretically been predicted for the thermodynamically unstable perovskite phase of YBiO. Here, it is shown that the crystal structure of t…
